INC., NEW YORK, "N, Y.; n CORPORATION or NEW YORK Y Foa' Terranova; orancrer-rs fron articlest A f A y Articles of' the rvmentioned fcharacterare n producedV by immersing formers, fgenerally 0f' glass, into 'arubber solution until a 4film Y of*V rubber of the Adesired thicknessfand chan acter aredeposite'd thereon. y The rubber is then vulcanizedupon the formers and removed therefrom.

`As these articles are extremely thin and delicate and :as they have atendency to adhere't'o the formersLthe greatest care must be exercisedin removingthem.lv

I have found that if these formers carrying the articles are revolvedaround their vertical axisO and passedduring their revolu# tion acrossthe face of an inclined revolving brush untila portion of each articleis re moved from a portion of its former and that then the revolvingkkform and A'its article be passed across the face of a revolving brushthe axis lof which isin a horizontalplane at right angles to thelongitudinal axis of' th'e former, the article will be readily removedfrom the former and that the article WhenV thus removed is in opencondition instead of in a rolled uppcondition Which resultswh'en thearticle is completelyremoved by the in clined brushes.v o n Theemployment of the last mentioned re; volving brush of my device has manypractical advantages and presents-a greatly improved method ofaccomplishing the desired results. l

When the articles are completely removed from their formers by means ofinclined brushes they are rolled up and turned inside out during theirremoval Which necessitates considerable manual laborin reversing eachone of them for commercial purposes.r By means of my device the articles'are removed in reversed condition but arenot rolled as i a-re thoseremoved solely by inclined brushes and hence their reversalv intocommercial condition is greatly facilitated. A further disadvantage inremovingy the :i articles by inclined brushesis that as the' 'formersfor some articles are of considerable length, the pressure of theinclinedV brush 'u-pon theextremity of'the former forces it from itsnatural vertical position, Astlie article lits tightly" upon the fac'e`of the'forf' mer, and as Lbecause of its delicate composition andcondition -itis absolutely essential that'it be 'removed as regularlyTand uniformly as possible to preventits being torn,

it is evident that'this distortion of the fro mer'from its normalposition during a part of'thev remova'lvvill result in of numerousarticles.

In my device-,the inclined brush operates Onlyupon that portion-'of theformer adjacentto its point of fixed connection with "the platformby,vvhich it is "carried and Vhence there is n'odlistortion of thepositionof the former, andthe remainder of' the removal is accomplishedby a revolving brush rvvhich abuts upon the former not fonly at. itsextended ypo'rtion removed from its fixedpoint, but up'onpractically theentire former, or upona very considerableportion of it, and hence theformer is maintained in its normal` vertical position during the entireremoval operation. 1 .f

When the former "is subjected to inclined brushes` only, Athat.portion-of the former from which the article has been removed is. notsubjected to any brush action and hence is not cleansed fromdeleteriousv mate;

being constantly lcleansed during the rev-` moval process, and ,my brushcontinually abuts upon the side face of the former from whichtheuarticle has been' removed. As it is essential that the former beabsolutely clean in order to allow a proper depositof rubber thereon,and as materials are added to assistv the removal Which materialsinterfer'e With the proper deposit of rubber upon the formers, ythevalue of my device is evident. I K,

I have further found that improved results can be obtained by entirelydispensing with the inclined brushes and employing only those' invvhichthe brush bristles move' the destruction gli . will describe one ofthem, the other being,`

in a plane parallel to the longitudinal axis h of the former, as shownand described, but

I prefer to use both kinds of brushes.

The above mentioned and other valuable attributes of my device will beevident upon a consideration of my specification and its accompanyingdrawings. y

In the accompanying drawings illustrating one form of the device of myinvention similar parts are designated by similar numerals.

Figure 7 is asection on the line 7 7 of Figure 6. v f' Figure 8 is`anrenlarged section on the line 8 8 of Figure 7 5 Figure 9 is adiagrammatic side view of myV device illustrating the removal of thearticles during the operation of the device. The particular form'of thedevice of my invention shown in the accompanyingdrawings comprises atable 10, supported by the legs 11,11.

Supported below the table top 1() are two parallel revoluble inclinedbrushes 12 and 12, and as these brushes and their operative mechanismscorrespond with each other, for purposes of clearness of description, I

designated upon the drawings with corresponding prime numerals.

The shaft 1 3 of the brush 12 is pivotally carried by the hanger14vwhich in turn is.

carried by the top 10. The other end of the shaft 13 is Acarried by thesleeve 15 which is pivotally attached to the vertically extended arm 16,which in turn is carried by the hanger 17 carried by the top 10. Thehanger 17 Y'is channel shaped within which the arm 16 is slidable,attachment between the two being accomplished by means of bolts 18, 18,passing through holes in the hangers and anelongated slotY 19 in the arm16. By these means the lower end of the brush 12 may bevraised andlowered as desired and fiXedly Y'positioned at any desired height. Theshaft 13 carries a sprocket 20.

Two pairsA of Vspaced parallel hangers 21, 22 and 21,.22 are attachedto-the top 10 andI as they correspond I will describe one pair of thesehangers and their operating parts, and indicate .the corresponding partsof the other pair of hangers and their operating parts by means of primenumerals.

The hangers 21 and 22 carry three revoluble shafts 23, 24, 25, eachcarrying at each end sprockets 26, 27 and 28.

The chain belts 29 and 30 passing around and meshing with the sprockets26, 26 and 28, 28 carry connecting slat members 31, 31 each of whichcarries a plurality of brushes 32, 32 and there is thus formed arevoluble curtain brush. The sprockets 27, 27 tend to keep the curtainbrush taut.

The sprocket 33 is connected by means of the chain belt 34 .to thesprocket 35 carried by the drive shaft 36. The gear 37 carried by theshaft 36 meshes with the gear 38 carried by thevshaft 39. The sprocket40 carried by the shaft 39 is connected by means of the chain belt 41 tothe sprocket 42 carried by the shaft 43. The sprocketf44 carried by theshaft 43 is connected by means of the chain belt 45 to the sprocket 46carried by the shaft 23. The revolution of the drive shaft 36,therefore, will revolve the two curtain brushes in oppositedirections.

The shaft 25 carries'the spiral gear 37 meshing with the gear 48 carriedby-thcl shaft 49, which latter carries the brush 50.

The shaft 23 carries a sprocket 51 which is connect-ed to the sprocket20 of the shaft 13 by means of Vthechain belt 52.

The shaft 53 carries the felt Wheel 54 and the sprocket 55, the latterbeing connected to a source'of revoluble power, not shown, by means ofthe chain belt 56.

lThe moving and revolving mechanism of the forms comprisestwo chainbelts 57 and 57 meshing with the sprockets 58 vand 58 carried by therevoluble shaft 59 and 59', the

chains passing over similar sprockets at the other end portion of thedevice, not shown. Both chains carry special supporting links e0, e0. If

The table carries two spaced opposed se'- ries of racks 61, 61, 61, 61.

The chain belts 57, 57 and the-racks 61, 61 are supported beneaththetable top by the two spaced parallel supports 62, 62'.'

A pair of pins as 63 carried by each rack section passes through anopening in its support 52, and is retained from dislodgement bythe'cotter-pin 64. A spring 65 carried by each pin 63 tends to press therack outwardly.

A plurality of former supports 66, 66 are attached to a platform 67,each former support carrying a pinion 68, capable of meshment with theseries of rack sections. Each former support carries a former 69,preferably of glass, the article 70 having been produced on the former.

A plurality of arms 71 pivotally carried at `the rubber articles thereonis moved` for-V wardly until it rests upon'the supports 60, 60, 60', 60of the chains 57, 57" which. then carry it forwardly, the sprocketsV 73,73 forcing the chain` against the; sides of .the

platform'in order to insure aregular move-` ment of .the latter. Thismovement vof the .platform causes the pinions `68, 68 to mesh l With therack sections 61, 61,161, 6l thus revolvingthe formers. The springs65,65 cause the 'pinions `to enter the racks and overcome anyinequalitiestliere may be in the platformssor. in .the positions of theformers thereon..

The action upon the. articles carried bythe formers :during this movingoperation is as follows, Aas is shown/in Figure V9, in Which thedashsline A B' represents. diagrammatically the upper extremity lof the.article 70 as it 4is gradually removed from its former 69:- `r- Thebrush l2 .gradually removes thearticle` 70 luntilit, the upper extremitythereof, has reached approximately mid-Way of the former. Itis evidentthat `ify this brushlQ were continued until it extended to the vbottom-of theformer, .the pressure upon the lower portion of 'the former Wouldpress` it from'its normal vertical position, thus .causing anunevenremoval of the article resultingin tearing or destroying it. fThey revolving formers are now brought into contact .with the revolvingand downwardly moving curtain rbrush v82 'which presses equally .uponpracticallyy the entire side face'of each former, the articles beingremovedv from .the formers and dropping.

into the chutet for further operations It Willv be noted that iftheientire remov al vvasaccomplished by an inclined brush 12, thatportion of. the formerr abovethe article would. not -beA cleaned, While4inv my` device the curtainy aproncleans the entire side face of theformers, the brush() cleans ythe closedH ends ofthe formersand the feltWheelt "dives them a final cleaning and polishing` D treatment.

It Will be further noted `that are removed in a practically opencondition, instead of being rolled up or turned inside out. I f

I do n ot limit myself to the particularisize,
